A Shape‐Based Model for Drag and Terminal Velocity of Non‐Spherical Plastic Particles

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Plastic pollution in rivers is governed by how individual particles move among the bed, the water column, and the free surface, processes that depend primarily on drag and terminal velocity. Although plastic particles span a much wider range of shapes than natural sediments, many existing drag and terminal‐velocity formulations still rely on ...

Exploring plastic transport dynamics in the Odaw river, Ghana

Frontiers in Environmental Science, 2023
Plastic pollution in rivers threatens ecosystems, increases flood risk due to its accumulations at hydraulic structures and its final emissions into the ocean threaten aquatic life, especially and probably most in coastal urbanized areas.

Plastic Hotspot Mapping in Urban Water Systems

Geosciences, 2020
Reducing plastic pollution in rivers, lakes, and oceans is beneficial to aquatic animals and human livelihood. To achieve this, reliable observations of the abundance, spatiotemporal variation, and composition of plastics in aquatic ecosystems are ...

Surfing Transport of Buoyant Objects Observed in the Nearshore

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Free‐drifting buoyant objects, including plastics, marine debris, and organisms, move with the wind, waves, and surface currents. These objects also surf on breaking waves; this process adds to the total transport of the objects and can control beaching.

Impact of Mangrove Forest Structure and Landscape on Macroplastics Capture

Marine Pollution Bulletin, 2023
Des réseaux complexes de racines et de troncs hors sol font que les forêts de mangroves piègent les déchets plastiques. Nous avons testé la relation entre les macroplastiques et la biomasse des arbres, l'abondance des racines, la géomorphologie des mangroves et la proximité de l'embouchure des rivières, en étudiant les marges terrestres et maritimes de

Presence and abundance of microplastics in the Thames River Basin, UK [PDF]

, 2015
The global increase in plastic production has led to growing concern about the environmental impacts of plastics and their degradation products. Microplastics have been extensively observed and studied in the marine environment but little is known about ...

A Critical Evaluation of Nano‐ and Microplastics: Sources, Health Risks, and Mitigation Strategies

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Microplastics (1 μm–5 mm) and nanoplastics (< 1 μm) have become ubiquitous contaminants across air, water, and soil systems, with growing evidence of their presence in human tissues including blood, lungs, and even the placenta. While microplastics have been extensively studied, nanoplastics remain poorly understood because of their minute size and ...

Characterization of Newly Discovered Polyester Polyurethane‐Degrading Methylobacterium aquaticum Strain A1

Journal of Basic Microbiology, Volume 65, Issue 10, October 2025.
ABSTRACT In this study, we present Methylobacterium aquaticum A1, a novel strain capable of degrading polyester polyurethane (PE‐PUR). The attachment of M. aquaticum A1 to PE‐PUR and its degradation capabilities were verified using Scanning Electron Microscopy (SEM) and Fourier‐Transform Infrared Spectroscopy (FT‐IR).
